A bottom-up approach provided by IPCC was developed for calculating the CO2 emissions from China's international seaborne trade sector during the period of 2001—2016. Based on the freight transport volume and considering the various commodities, shipping modes can be categorized into liquid bulk shipping, dry bulk shipping, and containers. The specified CO2 emissions were estimated referring to the considered shipping modes. The aggregated CO2 emissions were characterized to figure out the features during the study period. The decomposition analysis adopting Logarithmic Mean Divisia Index (LMDI) method was introduced to investigate the key influencing factors that initiated an impact on the CO2 emission changes in the China's international maritime activities. The results demonstrated that ①. The CO2 emissions from China's international seaborne trade witnessed a significant increase between 2001 and 2016. The short-term evolution trend did exhibit three different stages. ② The factors of per capita GDP and population size were proved to be the positive contributors all the time. The per capita GDP was served as the major force, which reflected the close correlation between the CO2 emissions and the economic development. ③ Energy intensity of vessels generated CO2 emissions during the study period and it had become the most powerful driving factor for the future CO2 emissions reduction in maritime transportation sector. The reduction of the marine transportation intensity appeared to be another inhibiting factor that contributed to the mitigation of the CO2 emissions. And ④ Under the business-as-usual (BAU) scenario without launching the new policies, CO2 emissions from China's international maritime transportation will keep on as an increase trend in the future. It is desirable for policy makers to develop future mitigation policies according to this work.
